How to use glyphosate to control soybean dodder? Please introduce the method of soybean dodder is a parasitic weed on soybean, also known as rootless Teng. After sowing and emergence of soybean, dodder seeds in the soil also began to germinate. after the young stem extended to the soil surface, the nutrition of soybean plant was absorbed, the flowering and pod of soybean decreased, and when serious, the whole plant of soybean withered, which had a great effect on the yield and quality of soybean. In the past, we used Acetochlor, Rasol and dimethamine respectively before and after seedlings, but the effect was not very satisfactory. in recent years, farmers in soybean producing areas used glyphosate to control dodder. Good results have been achieved. The control effect is generally more than 85%. The principle of using glyphosate to control dodder is mainly based on the difference of glyphosate resistance between parasitic and host plants, that is, soybean has strong resistance to glyphosate and can tolerate a certain range of drug concentration, but dodder has poor drug resistance. The method is to spot pieces in the field shortly after the emergence of dodder seedlings and in the early stage of soybean damage. When it is found that there is a dodder disease center, use 10% glyphosate 400 times dilution to spray on the soybean plants in the disease center, spray evenly, do not miss spray. A large number of dodder died 10-15 days after spraying. However, at 3-4 days after treatment, the young leaves of soybean began to yellowing, that is, there was slight drug damage, but it had no great effect on its growth and development. after about 7 days, the etiolated plant rate stopped expanding, and all the young leaves turned green in about 10 days and returned to normal growth. In addition, it should be noted that due to the continuous occurrence of dodder in the field, it should be checked and treated again about two weeks after the first use of the drug, in order to achieve the purpose of thorough control.
